Which way will water molecules move if a red blood cell is placed in distilled water?.
Stels [109]

Answer:

<u>If you put a red blood cell in distilled water (100% H2O), there will be a net movement of water </u><u>from a region of higher concentration (100%) to a region of lower concentration </u><u>(the cell with 99.15% H2O). The distilled water outside the red blood cell, since it is 100% water and no salt, is hypotonic (it contains less salt than the red blood cell) to the red blood cell. The red blood cell will gain water, swell ad then burst. The bursting of the red blood cell is called hemolysis.</u>

What is likely negative affect on the earth extra carbon dioxide is added to our atmosphere
konstantin123 [22]

Answer:

It will change weather patterns and destroy ecosystems.

Explanation:

Carbon dioxide, while not being the most power, is the most common greenhouse gas. A greenhouse gas helps to trap longwave radiation from leaving the Earth’s atmosphere and is enhancing global warming. We say enhanced global warming due to the Earth warming through natural reasons too. Several changes occur due to this temperature increase. Sea ice melting causes freshwater to enter the sea. An increase in sea levels can cause coastal flooding, increased erosion and a higher frequency and power of storms. Water density is linked to salinity. By introducing more freshwater the salinity decreases in the north and south of the Earth. If the oceanic currents change this will cause the weather to become more extreme during seasonal changes in many regions around the world. While humans can adapt their living conditions to suit the climate, many animals and plants can not. Therefore, enhanced global warming will cause the loss of many ecosystems around the world, including coral reefs.

When you take the exit ramp off the expressway and merge onto the next road, you see yellow lines dividing the roadway. What do
alexandr402 [8]
Yellow lines means that roads are merging and there's going to be traffic coming, so it's a warning to be cautious and to join the merged road. It's usually a warning to people that are going at a high speed in their vehicle. So merging majorly helps prevent an accident.
